bifocal

They use bifocal glasses, as might a lot of us soon.

He may also have prisms, progressive bifocals, and so on, which don't cost $30.

The problem that bifocals fix is the distance from 20" to the eyes or near vision!

Tried the bifocal progressives and the top half was fine but bottom was like looking though coke bottles.

They're great for people with poor eyesight, especially older people who won't admit they need bifocals.

Even my regular ones are weighted, and you can do the same there to achieve the same results as regular bifocal glasses.

Some sort of adaptive bifocal technology that watches your eyes and auto focuses might be the first winner.

This type of technology is similar to what a progressive or "no-line" bifocal does at present.

Progressive lenses can be really tricky to get used to from what I’ve been told, you may want to give cheaper bifocal lenses a try first or just buy a pair of reading glasses you take on and off. If you feel they aren’t your thing you would feel less shelving the cheaper option first.

I have progressive bifocals to get some amount of varying correction with distance, but this is thrown off for computers since they take up more of your field of vision than a book.

Old people also have bad eyesight and often wear bifocal lenses for reading, and looking up and down constantly between a keyboard and a screen is taxing and frustrating.

Spend time sympathetically observing and you'll likely come to see everything through a kind of cultural bifocal - The western interpretation as seen in TFA constitute a legal definition of personhood and boards being established to provide a voice for Te Uruwera and the Wanganui river respectively.
